Describes the graphic construction of lunar eclipses and how lunar graphics are used. The meaning of some terms and concepts and a diagram for a total lunar eclipse are also included. (HM)

This pamphlet presents a series of photographs depicting the story of the Apollo 8 mission around the moon and includes a brief description as well as quotes from the astronauts. The photographs show scenes of the astronauts training, the Saturn V rocket, pre-flight preparation, blast off, the earth from space, the lunar surface, the earth-based…

Reviews short term lunar surface changes gathered during the last decade and their relations to the seismic data from the four seismographs placed on the Moon. Indicates that such a continued consideration may give rise to a new insight into the structure of the Moon. (CC)

Evaluates the effect of the Apollo program on the geology of the Moon to determine further study problems. Concludes that the National Aeronautics and Space Administration can provide excellent justification for its extension since human beings have the possibility of using the rocks in ways not currently conceived. (CC)

Presents current ideas about the fission process of the Moon, including loss of mass. Saturnian rings, center of the Moon, binary stars, and uniformitarianism. Indicates that planetary formation may be best explained as a destructive, rather than a constructive process. (CC)

Summarizes the scientific activities of the Apollo program, including findings from analyses of the returned lunar sample. Descriptions are made concerning the possible origin of the moon and the formation of the lunar surface. (CC)

Describes the origin of the Moon on the basis of the Apollo expeditions as an accumulated gas sphere at its very beginning and, later, a satellite captured by the Earth. Indicates that the model would be substantially believable if further observations should be proved to exist as estimated. (CC)

Summarizes chemical information about the lunar surface on the basis of experiments performed in orbit and analyses of lunar soil and rocks. Indicates that the Apollo program completes chemical mapping of about 20 percent of the Moon with 80 percent remaining to be solved in the future. (CC)
